The invention relates to the field of petroleum, in particular to a drill bit cleaning device for oil exploitation. The drill bit cleaning device achieves the following technical effects that the speed of cleaning a drill bit is relatively high, cleaning is relatively thorough, and a worker does not need to face the drill bit during cleaning, and therefore the worker cannot be hurt when silt is splashed. According to the technical scheme, the drill bit cleaning device for the oil exploitation comprises a bottom plate, a right support, a motor, a rotating shaft, a fixing plate, a supporting rod, a first bearing block, a sliding rail, a sliding block, a spring, a clamping plate and the like; the right support is arranged on the right side of the top of the bottom plate, the fixing plate is arranged at the top end of the right support, and the motor is arranged on the upper portion of the left side of the right support. According to the drill bit cleaning device for the oil exploitation bit, the drill bit is clamped by the clamping plate, then the motor works to drive the rotating shaft to rotate, then the drill bit is driven to rotate, meanwhile, a spray head is used for spraying water, and the drill bit can be cleaned in an omni-directional mode; and a brush can brush the drill bit so that the drill bit can be more thoroughly cleaned, and then the effects that the speed of cleaning the drill bit is relatively high, and cleaning is relatively thorough are achieved.

The invention discloses a dynamically-controlled filament breakage secondary automatic compensator, which comprises a first thread make-up gun and a second thread make-up gun; wherein, the two thread make-up guns are provided with thread make-up sensors respectively, the sensors of the first thread make-up gun and the second thread make-up gun are connected with PLC which is used for receiving signals from the sensors, PLC is connected with the first thread make-up gun and the second thread make-up gun which receive the instruction from PLC, PLC is connected with malfunction alarm devices of the first thread make-up gun and the second thread make-up gun. The invention has the advantages of reasonable structure and fine work effect.

The invention belongs to the technical field of hydrological monitoring equipment, and specifically discloses a circulating cableway radar wave flow measurement system, which includes an installation mechanism, a guide mechanism, a flow measurement mechanism and a traction mechanism. On both sides, the guide mechanism includes a guide wire rope, and the two ends of the guide wire rope are respectively installed on the mounting plates on both sides; The sliding hole for the guide wire rope to pass through, the upper side of the inner wall of the sliding hole is rotatably connected with a number of rollers, the lower side of the inner wall of the sliding hole is installed with a first sponge block, the sliding plate is provided with a mounting groove and an oil chamber, and the oil chamber is vertically slid and connected with For the second slider, a driving member for driving the second slider to slide is installed on the upper part of the oil chamber; the traction mechanism is used for pulling the sliding plate to slide. By adopting the solution of the invention, the problem that the guide wire rope is easily rusted by water vapor erosion can be solved.
